Teaching computer science with clarity.

I am Sarfraz Raza, an educator and researcher working across algorithms, computational geometry, programming, and immersive learning. My focus is simple: make difficult ideas understandable without making them shallow.

Key points

More than twenty years in the classroom.

Teaching foundational and advanced computer science across ITU, LUMS, FAST-NUCES, UCP, and Namal College.

Research grounded in algorithms and geometry.

Work spanning computational geometry, selection lemmas, centerpoints, and I/O-efficient algorithms.

Course material designed for real students.

Structured archives, examples, and explanations that support learning beyond a single lecture.

Technology used to clarify—not distract.

From parsers and machine translation to virtual laboratories, tools are selected around learning outcomes.

About

A career built around research, teaching, and explanation.

Academic depth presented through a practical, student-centered approach.

Clear thinking belongs in both the research lab and the classroom.

I picked up Computer Science at NUCES Lahore not knowing it would turn into a lifelong habit of explaining things for a living. An MS at LUMS pulled me into computational geometry under Dr. Nabil Mustafa, and a research studentship at Aarhus University, under Lars Arge, taught me to think in I/O-efficient algorithms. Somewhere along the way I realised what I actually loved wasn't just solving the problem — it was watching a student's face when they finally see it too. That's what's kept me at the front of a classroom for over twenty years, currently as a Teaching Fellow at ITU, and before that across FAST-NUCES, FOIT-UCP, and Namal College.

My education

MS (CS), 2008–2010 — School of Science & Engineering, LUMS Pakistan. I focused on Theoretical Computer Science: Algorithms, Discrete Mathematics, and Computational/Discrete Geometry.

Research Studentship — Aarhus University, Denmark, where I worked under Lars Arge on I/O-efficient algorithms.

BS (CS), 2001–2005 — National University of Computer and Emerging Sciences (NUCES), Lahore, where it all started.

Languages I teach & speak in

English, Punjabi, and Urdu — I move between all three in the classroom, because a concept should never get lost in translation if I can help it.

A few things I'm proud of

Best Teacher Award (UCP, Fall 2017) · Best Teacher Award (Namal, Fall 2012) · Best PhD-Presentation Award, MADALGO, Aarhus University (2015).
